Specification of Letters Patent.

Patented neat, 1909.

No Drawing. Applicatio'nfiled March 1, 1907, Serial No. 359,994. Renewed May 7, 1909. Serial No. 494,585.

Be it known that I, WALLACE A. BEAT Y,

' a citizen of the United States, residigg 11? saponaceous element in such a manner as to I the city, county, and State of. New

have invented certain new and useful Improvements in Antiseptic Soap, ofwhich the following is a full, clear, and :BXflCi) de-' scri tion.

y invention relates to anew and useful soap, the purpose ofxmy invention being to impart to said soap an antiseptic and germicidal property, which property is iven theretoby means of an-antisepticormed of a compound of bromin and cresol, which compound contains substantially 7 5 per cent. or bromin. This antiseptic, I have discovered, is in strength from-one hundred to two hundred and fiftv times. as strong, as carbolic acid, which is thefgeneral ac. cepted standard. It also lacks toxic, irritate ing and odorous properties. It also, as I have discovered,i s stable and by reason of,

the several advantages combines with the maybe employed in many cases where itwould be dangerous, if-not impossible, to

I employ soap impregnated with any of the well known antiseptics now commonly employed. As compared with the standard antiseptic, it is well known that carbolic acid is of doubtful value when used in a strength of less than 5 per cent. To impre'gnate a soap with a5 per cent. solution of carbolic acid would be to render the soap not only offensive but extremely dangerous in actual use where the skin is at all subject to the influence of an irritant. Furthermore,

in orderto produce a soluble mixture when carbolic acid is employed, a quantity of alkali equal substantially to per-cent. of the quantityofccarbolic acid used is .necessary, thereby increasing the irritating properties of the soap as such by the presence of thisexcessive-quantity of alkali. Because of g the. superior strength and non-irritating.

progierty of my antiseptic, the same may be emp 7 as'such eflectively antiseptic. Furthermore,

requiring a very much smaller percentage oithe antiseptic element to render the soap,

oyed to. great advantage ina snap, it.

stantially one-fifth as much alkali 'to produce a solution of my antiseptic as is required to produce a solution of carbolic acid, thereby practically eliminating irritating properties. In other words, whereas in the production of antiseptic soaps with the use employed, .it requires the introduction of an excessive and dangerous quantity of alkali, by the use of my improved antiseptic no excess of alkali is required. By practical experimentation I have discovered that a soap containing as small a quantity as one per cent. of my antiseptic will kill the most resistant form of bacteria, 2'. e. anthrax spores.

' The preferable way of making the soap is as fOllOWSIflZd parts of tetra-brom-cresol are added to 40 parts of caustic soda dissolved in 400 parts of ater. This solution is evaporated in a str am of air free from carbon-dioxid or in a' vacuum: The solid alkali salt is thus obtained. Potash may caustic soda. The, antiseptic soap in solid form is prepared by adding the salt of tetrab'rom-cresol to soap-in the proportion of one pound thereof to' ninety-nine pounds of soap- The addition to the soap is preferably made while the soap is in a molten condition before framing.,-Obviously this compound may beincorporated in the soap in any of the well known manners now employed, and the soap :ma likewise be either liquid or solid, as desire WhatIclaim is: p.

1. An antiseptic soap combining a saponaceous element and tetra-brom-cresol.

2. An antiseptic soap combining a saponaceous element and a compound of bromin and cresol, which compound contains substantially 7 5 of bromin.

#3. A detergent combininga saponaceous element and an antiseptic having tetra brom-cresol as its base.
